HOW TO WIRE THOSE DAMNED COMPUTER FANS TO A WALL SOCKET!
K guys. I am baked. but I will try to instruct you all on this sunday afternoon of how to properly wire a 12v computer fan to a standard 9v power supply from a cell phone.
Yes. this is 3v lower then what the fan says.
This will slow the fan a bit and lessen the noise! trust me its awesome!
If you wire a 9v fan to a 12v power supply you will smoke your fan faster than a waterfall bong. Dont do it.
Materials:
-Scissors (If your really fancy, wire splicers. expensive, but strip a real nice wire)
-12v Computer fan
-electric tape.
Step 1 : Gather materials.
Step 2 : Remove any input end from the adapter. doesnt matter what the tip is as long as your power supply has 2 wires (copper or silver) and your fan has 2 wires.
REMEMBER: Your supply must be a Lesser voltage than your fan or you will BURN YOUR FAN OUT.
Step 3 : Your fan will have 2-3 wires. Red and black are important, Yellow is speed control. I dont know how to wire that one, so Just tie it off for now. Strip all 4 exposed ends (2 from ac adapter, 2 from fan(red and black)). With scissors, simply cut through the plastic without cutting through the metal. this can take patience. I use scissors as I am too cheap for wire cutters. This wire is ready to have the plastic coating pulled directly off.
When you are done , you should have this.
Step 4 : when you have your wires stripped , you can now test the charge of your fan.
Warning: Shock hazard.
Plug in your ac adapter, being careful not to touch the exposed ends of power. Now touch one ACend to the black wire on the fan and one ACend on the red wire. If the fan turns, you have the wires correct. Some fans will turn both ways, some wont. Some turn better one way. some dont matter. figure out which cable goes to which side and tape it off.
(p.s. if you shock yourself with a 9v power supply, itll be about the same as sticking your tounge on one of those batteries. not pleasent, but not deadly. I strongly discourage electrocuting yourself in any extent however.)
Step 5: Braiding wires : Now that you have your wires figured out, start by making one turn around a wire midway through both of your stripped ends.
Tip: The more exposed end you have, the better a braid you can make. however the harder it will be to cover up later, and make look sloppier. I recommend an inch.
Step 6 : Continue to wrap the exposed wire around the opposite wire, living 1/2 the wire free and unwrapped above your braid.
Step 7: Once your first braid is complete, fold back your loose end and braid it overtop of the braid you've already done.
Step 8 : Take a small Piece of electric tape, putting the wire as close to the edge as possible. Now carefully wrap this around till you have a secure seal over the plastic. Ensure that there is electric tape overlapping platic wiring on EITHER side of your braid. the more, the merrier.
What you should have now :
Step 9 : Cleaning it all up : This is where you can do what you will, mount it to a hood, light, anything. always keep common sense in mind. lights are hot. wires are not meant to be. don't put wires directly on bulbs or in huge heat areas!.
Hereswhat I did with mine. It will be blowing directly on the plants, So I just needed to clean up my wireing and ensure no loose ends. here it is :
